+# 此刻五层记忆
+
+此刻不会把所有历史一次性塞给模型。它将本机上下文分成五层，先判断时效和项目相关性，再为当前建议或 Codex 工单检索少量相关片段。
+
+| 层级 | 保存什么 | 生命周期 | 主要用途 |
+| --- | --- | --- | --- |
+| 当前任务记忆 | 正在处理的任务、负责人、截止时间、Loop、会后 Todo | 短期；完成或过期后清理 | 判断此刻最该推进什么 |
+| 项目上下文记忆 | 项目目标、阶段、进展、依赖、风险与来源 | 随项目刷新 | 让建议落到正确项目与阶段 |
+| 用户偏好记忆 | 沟通、工作、视觉、介入强度与交付偏好 | 稳定；由明确反馈校准 | 决定怎么说、何时介入、哪些建议该静默 |
+| 技能与经验记忆 | 可复用工作流、验证方法、失败教训 | 长期复用 | 选择正确的执行与验收方式 |
+| 长期知识与决策记忆 | 跨项目知识、关键决策与版本关系 | 长期；新结论可覆盖旧结论 | 保持长期协作的一致性 |
+
+## 工作方式
+
+1. 启动时增量检查本机 Codex 画像、使用经验、当前记忆摘要和长期记忆索引。
+2. 每次只读扫描后，用飞书未完成任务、会后 Todo、Codex Loop、Chronicle 与本地项目活动刷新前两层。
+3. 生成建议时仍以实时来源为准；记忆只参与理解、排序、去重和执行方式选择。
+4. Codex 接手任务前，按任务语义和项目检索相关记忆，并以明确的非指令上下文注入工单。
+5. 用户的采用、不重要、已过期和好坏反馈进入偏好校准；重复负反馈可压低或关闭同类建议。
+
+## 隐私边界
+
+- 记忆文件只写入当前用户的应用数据目录，目录权限为 `0700`，文件权限为 `0600`。
+- 安装包和 Git 仓库不包含任何用户记忆、会话、工作项目、浏览记录或反馈记录。
+- UI 只接收每层数量、同步状态和隐私说明，不返回记忆正文。
+- 记忆不能覆盖当前指令、权限边界或实时 source of truth；外发、共享写入和删除仍需明确授权。
+
+## 本地同步
+
+安装版会在启动时自动增量同步。开发者也可以显式运行：
+
+```bash
+npm run memory:sync
+```
+
+可用 `-- --data-dir /absolute/path` 指定测试目录。命令只输出各层计数，不打印记忆正文。
